A Suitable Control Strategy for Source Converters and a Novel Load- Generation Voltage Control Scheme for DC Voltage Determination in DC Distribution Systems

The power flow control in DC distribution systems is achieved by source converters which have DC voltage controllers. This paper proposes a suitable control strategy for source converters which has a DC voltage droop controller and a novel instantaneous power regulation scheme. Furthermore, this paper develops a simple method, named load-generation voltage control (LGVC) scheme, which can be used for DC system voltage determination. Simulation results indicate the effectiveness of the proposed control strategy for source converters and the LGVC scheme.
